Hi folks,
Can someone tell me how to wire up the green and red led to the lipo charger module please?
I have the charger working fine, it's charging my battery, but can't figure out how to get the charge indicators to work!
I know I'm missing something very obvious but I just can't see it!
Thank you in advance
Iain

Hi there, 
Thanks for the quick reply! 
Sorry, I didn't mention the board type, its the 'Improved Lithium Charge Module - 1 Amp Version'
Cheers,
Iain

The RED and GRN pads connect to GND when they are going to be lit. To get an LED to light, the cathode of the LED would get connected to the RED or GRN pad, and the anode of the LED would get connected to IN+. A resistor needs to be connected to the LED (at either the cathode or anode side) to prevent damage to it, otherwise it will get 5v directly and burn out pretty quickly.
